Amol Fasale edited comment on CASSANDRA-2103 at 4/5/14 10:03 AM:
-----------------------------------------------------------------

Agreed with Nikolay, counters should have TTL values, but only once insertable, should not
be updatable (Only when initializing the counters). Next time whenever counters increments,
should ignore the TTL.

Usecase like, when we are maintaining a realtime counters, like daily page views, next day
these becomes useless, should not have any point keeping this unnecessary data and increasing
overhead.
